This paper presents the simulation results of potential distribution and electric field distribution 66 kV insulator. For this work Finite Element Method is used. COMSOL Multiphysics software is used to carry out simulation results. Silicon rubber is used as insulating material and Alumina is used as a filler material to construct composite insulator in COMSOL. In this analysis four cases are compared for unfilled case and filled 1) Without Pollution Layer and Without Water Droplets 2) With Pollution Layer and Without Water Droplets 3) Without Pollution Layer and With Water Droplets 4) With Pollution Layer and With Water Droplets. The simulation results shows that after adding fillers in the insulator electric field magnitude near to the terminals reduces in composite insulator compared to the unfilled insulator.
